AWN IN G-ROLLER AUTOMATIC STOP.

Application filed February This invention has relation to certain newand useful improvements in an awning roller automatic stop and has forits primary object the provision of a structure which is of simpleconstruction and operation as well, and whlch may be I as highlyeflicient in use,

employed for practically all awnings.

The invention has for another object the provision of an awning rollerautomatic stop which may be readily adjusted to cause automatic stoppingof the rotation of the roller when the awning is unwound suiiiciently,thus preventing wrapping or winding of the awning canvas in the wrongdirection around the roller.

The invention has for its further object the provision of an awningroller automatic stop which is composed of the minimum number of partsof simple construction and arrangement and which will be highlyeificient in use. I

With the foregoing and other objects in View, as will appear as thedescription proceeds, the invention resides in the construction,combination and arrangement of co operating elements as hereinafter morespecifically set forth, claimed and shown in'theaccompanying drawingsforming a part of the present application and in which:

Figurel is a perspective view of the roller in use. i

Figure 2 is an enlarged perspective View of the roller, removed and withparts broken away.

Figure 3 is a fragmentary sectional view through the roller.

Figure 1 is a View similar to Figure 3,,

showing a' slightly modified form of the invention.

Figure 5 is a transverse section, substantially on the plane of line 55of F igure 4, looking in the direction indicated by the arrows.

Referring more in detail to the drawing, in which similar referencecharacters designate corresponding parts throughout the several views,it will be noted that the shaft of the roller is composed of sections 10and 11, which are supported respectively in bracket bearings 12 and 13.The bracket bearings 12 and 13 have oppositely directed base portions orflanges 1 provided with suitable openings 15 to receive attachingmembers through the medium of the bracket bearings 12 and 13 may befirmly secured upon a wall or other support, as will be readily under- Ithe roller core 19 7 tion 21 of the shaft 2, 1926. Serial No. 85,461.

"stood by referring to Figures 1 and It will also be seen from theseviews that the awning canvas 16 is wound upon the roller outer sleeve 17in the usual manner or unwound from this sleeve by operation of thecontrol shaft 18, the upper end of which 1 extends intothe bracketbearing 12 and has appropriate driving means with the shaft sectionrlO.The shaft section 10 is rigid with the roller outer sleeve 17 and theroller core 19, on which the sleeve 17 is firmly mounted; v a

The shaft section 11 is adapted to be locked into the bracket bearing 13after adjustment, as will be later more clearly under- 20 or" otherapprostood, by a cotter pin priate means, thus preventing rotation ofthe shaft section 11 during winding and unwinding of the awning canvas16. The shaft sec tion 11 extends in and through the end of and isprovided with a threaded portion 21 extended through the elongatedpocket 22 provided in the roller ace of core 19 and; opening upon theinner the roller sleeve 17, the core 19 being practically of rectangularform in cross section throughout the greater portion of its length. Theinner end of the shaft section 11 is extended through the transversepartition 23 in the core 19 and into the smaller orauxiliary pocket 24,a roller 25' being then s'ecured upon the same, within the pocket 24 andfirmly held on the inner end of the shaft section ll-by a pin 26 or'thelike extended through the collarf25 and through the inner end of theshaft'section 11', as clearly shown in F igures-2, 3and 4 of thedrawings. stop nut 27works upon the threaded persection 11 within thepocket 22 and travels back and forth on the shaft section 11 from oneend to the other of the elongated pocket 22, the walls of the pocket22preventing turning of the nut 27 within the pocket 22. It will thereforebe seen that rotation of the roller in either direction may be regulatedby proper adjustment of the shaft section 11 to place the nut 27 acertain distance from one end of the pocket 22 before placing the cotterpin 20 through the bracket bearing 13 and the outer portion of the shaftsection 11 as shown in Figure 2.

In the modified form of the invention shown in Figures 4: and 5, thecore of the roller is constructed similar to the preferred form with theexception that it has a cap A IL w an awning canvas 29 provided on itsouter end with an annular flange 29 carried thereon to receive thereduced end 28 of the halves or longitudinal sections 28 of thesectional or twopart roller sleeve 17 which in this form may be made ofwood or other appropriate material.

In both forms of the invention, the sleeve 17 may be secured to the corenear the ends of the latter by appropriate bolts 30, as illus trated inFigures 3 and 4, to thus cause rotation of the core 19 with the sleeve17. It is believed the complete construction and operation ofthe'invention may now be apparent from the foregoing paragraphs taken inconnect-ion with the accompanying without further detailed description.It may be briefly stated, however, that the stop nut 27 may be readilyadjusted on the threaded portion of the shaft section 11 or 11 eitherbefore or after mounting of the roller in the bracket bearings providedfor the end shaft sections 10, 11 or 11 The pin 20 may then be passedthrough the outer end of the sections 11 or 11' and through the bracketbearing in which such shaft section is mounted, thus holding the shaftsection 11 or 11 against rotation in its bracket bearing 13. Duringwinding and unwinding of the awning canvas 16 on the sleeve section 17,the stop nut 27 will work back and. forth on the threaded portion of theshaft section by which it is carried and within the pocket 22 of thecore 19, the stop nut 27 finally striking upon one end wall of thepocket to prevent further rotation of the roller sleeve 17 andconsequently winding or unwinding of the 16. A slight change of theadjustment of the nut 27 may be made by withdrawing the pin 20 andturning the.

shaft section 11 or 11 with respect to other parts of the rollerstructure and then replacing the pin 20 to prevent further independentrotation of the shaft section 11 or 11*. This adjustment of the nut 27will permit increase or decrease in the winding or unwinding of theawning canvas 16 as the roller sleeve 17 drawings tails of construction,

and core 19 are operated in the usualmanner, It is also apparent that aroller constructed in accordance with this invention will eliminatedanger of the awning canvas 16 being only partly unwound or being woundupon the roller sleeve 17 owing to continued rotation of the roller inthe same direction after complete unwinding of the awning canvas 16.Furthermore, when the present form of roller is employed,

in the wrong direction danger of the canvas awning 16 sa gingb whenunwound, is overcome.

While the preferred embodiments of the invention have been disclosed,'t; is to be understood that minor changes in the'derangement-ofcooperating elements, may be resorted to withinthe scope of what 1Scombination and ar claimed without departing from the spirit of theinvention.

hat is claimed is v A device of the character described in. cluding aroller sleeve, a shaftrsection rigid with one end of said sleeve, aremovable core fitted in the opposite end of said sleeve and securedthereto, said core having spaced pockets formed therein, a second shaftsec.- tion loosely journaled in said core and extending longitudinallythrough said pockets and threaded for a portion of its length, bracketbearings supporting the outer ends of said shaft sections, said secondshaft section being normally secured in said bearing against movement,means for rotating said roller sleeve and a nut working on the threadedportion of said second shaft, being disposed in one pocket contact withthe side walls thereof, whereby the rotation of the roller will causethe nut to travel on said shaft, said nut limiting the' rotation of theroller upon contact with the end walls of said pocket, said second shaftbeing releasable from its bracket bearing to permit adjustment of saidnut on said shaft.

In testimony whereof I afiix my signature.
